The Company File version is not supported

We have been unable to update our API on our W10 server now for 6 months.  Each upgrade goes OK until we come to the API part which invariably fails.

Now when I try to access the API it is failing with the message

"The Company File version is not supported."

I have attached an error log file from 2020-08-22 which displays the issue.

I cannot find any way to uninstal the |other version" of the api which according to the messages is blocking our ability to instal the newer version of the api.

This forum won't let me supply the .txt log file (??????  yet another buggy MYOB product ????)

Here is the log file cut and pasted.
